Best ResponseYou've already chosen the best response.0\[b^3=1000\] \[3\sqrt{b^3}= 3\sqrt{1000}\] b=10

Best ResponseYou've already chosen the best response.3well did you take 3rd root right ? you can write 1000 in terms of 3 exponents

Best ResponseYou've already chosen the best response.0What is the point of the 3's in front of the square root signs?

Best ResponseYou've already chosen the best response.3that's not 3 it's a 3rd rooot i guess like this \[\huge\rm \sqrt[3]{b^3}\]

Best ResponseYou've already chosen the best response.0Right, I didn't know how to do that

Best ResponseYou've already chosen the best response.3you can convert 3rd to 1/3 exponent \[\huge\rm \sqrt[3]{b^3} = b^{3 \times \frac{ 1 }{ 3 }}\] so cancel out 3 exponent u have to take 3rd root :=)

Best ResponseYou've already chosen the best response.3\[\huge\rm \sqrt[3]{b^3} = b^{\cancel3 \times \frac{ 1 }{\cancel 3 }}=b\]

Best ResponseYou've already chosen the best response.0Wouldn't that also mean that 1000 would be multiplied by 1/3?

Best ResponseYou've already chosen the best response.3yes so 1000 can be written as 10 to the 3rd power \[\huge\rm \sqrt[3]{10^3}\]

Best ResponseYou've already chosen the best response.0See that's where I get confused, so the 1000 get simplified down to 10 because?

Best ResponseYou've already chosen the best response.3because it's easy to solve without calculator and it's legal :3

Best ResponseYou've already chosen the best response.0_ so because 10^3=1000 it gets simplified to 10^3 and since it's the 3rd root the exponent cancels out leaving b=10 ?

Best ResponseYou've already chosen the best response.3b to the 3rd power so you can either write 10 to the 3rd power or put 3rd root of 1000 into the calculator :=)

Best ResponseYou've already chosen the best response.0See when I enter that into my calc I get 94.86....

Best ResponseYou've already chosen the best response.3and it's helpful when you have to find an exponent given base for example 10^x = 1000

Best ResponseYou've already chosen the best response.0\[3 \sqrt{1000} \neq \sqrt[3]{1000}\]

Best ResponseYou've already chosen the best response.0Yea see I don't know how to enter the latter

Best ResponseYou've already chosen the best response.3it's not 3 times square root of {1000} 3rd root like \[\sqrt[3]{1000}\]

Nnesha

Best ResponseYou've already chosen the best response.3ohh then convert 3rd root to 1/3 exponent \[\huge\rm \sqrt[3]{1000} = (1000)^\frac{ 1 }{ 3 }\]

Best ResponseYou've already chosen the best response.0That works. =] Could you possibly help me with another problem?
