Question 362169
I think you mean >> {{{ (23^3)^7 *(7^2) }}}

You can not do many things in this problem the only thing is just a multiplication of the square's such that 7*3 and the equation will look like >>

{{{ (23^21) *(7^2) }}} The remaining part is just calculation by a calculator.

Let me give you another example such that : {{{ (2^3)^7 *(8^9) }}}

First you will force to make the numbers under the square same,if they are multiplication of same number. In this question 2 and 8 are come from 2. So that,you will make the numbers under the square 2. Observe this >>

{{{ (2^3)^7 *((2^3)^9) }}} You wrote 8 as 2^3 after then you'll multiply the upper square parts as 7*3 and 9*3 and you'll get >>

{{{ (2^21)*(2^27) }}} After then (it's a rule) you'll sum 21 and 27 and write as

{{{ (2^48) }}}
