Annabelle and Navene are multiplying (4275)(4372).
Annabelle's Work Navene's Work
(4275)(4372) = 42 + 375 + 2 = 4577 (4275)(4372) = 42⋅375⋅2 = 46710
Is either of them correct? Explain your reasoning.

Best ResponseYou've already chosen the best response.0@freckles it means like its an exponent so i guess its raised

Best ResponseYou've already chosen the best response.0hint:we can write this: \[\large \left( {{4^2} \cdot {7^5}} \right)\left( {{4^3} \cdot {7^2}} \right) = \left( {{4^2} \cdot {4^3}} \right)\left( {{7^5} \cdot {7^2}} \right) = {4^{2 + 3}} \cdot {7^{5 + 2}} = ...?\]

Best ResponseYou've already chosen the best response.0as I wrote before, your expression can be rewritten as below: \[\large \left( {{4^2} \cdot {7^5}} \right)\left( {{4^3} \cdot {7^2}} \right) = \left( {{4^2} \cdot {4^3}} \right)\left( {{7^5} \cdot {7^2}} \right) = {4^{2 + 3}} \cdot {7^{5 + 2}} = ...?\]

Best ResponseYou've already chosen the best response.0so then when there not like bases how do u multiply it?

Best ResponseYou've already chosen the best response.0we have to compute the explicit value of each power and then we have to multiply them together

Best ResponseYou've already chosen the best response.0for example: \[\large \begin{gathered} \left( {{4^2} \cdot {7^5}} \right)\left( {{4^3} \cdot {7^2}} \right) = \left( {{4^2} \cdot {4^3}} \right)\left( {{7^5} \cdot {7^2}} \right) = {4^{2 + 3}} \cdot {7^{5 + 2}} = \hfill \\ \hfill \\ = 1024 \cdot 823543 = {\text{843}}{\text{,308}}{\text{,032}} \hfill \\ \end{gathered} \]

Best ResponseYou've already chosen the best response.0so u just multiply the bases and then the exponents together right?

Nnesha

Best ResponseYou've already chosen the best response.2you question is when bases are not like then how would we multiply it ? if bases are not same you can't multiply or add the exponents \[2^2 \times 3^5= 2 \times 2 \times 3 \times 3 \times 3 \times 3 \times 3\]

Best ResponseYou've already chosen the best response.0no, I'm sorry, you have to evaluate each power first, then you have to multiply the obtained values together
