$49^{3/2}=\sqrt{{49^{3}}}$

4. anonymous

yea i see that. but i got some huge number.w hat do i do then?

5. anonymous

$\sqrt{49^3}=\sqrt{49\times49\times49}=\sqrt{49}\times \sqrt{49}\times \sqrt{49}=7^3$$7^3 = 7\times7\times7=49\times7=343$

7. anonymous

You can do that, but don't forget to take the square root of 49*49*49.
