Answer:
(a) 39
(b) 63
Explanation:
(a) 4^3-5^2
In this kind of equation, ensure that the square on each of the figures is well treated
Deal with the square first before dealing with the given equation
Here it's goes
4^3 means cube of 4 which means 64
5^2 means square of 5 which is 25
Back to the question
4^3-5^2
64-25
=39
Therefore the final answer is 39
(b)6^2+3^3
Which means 6^2 square of 6 and it equals to 36
3^3 means cube of 3 which equals to 27
Back to the question
6^2+3^3
36+27
=63
Therefore the final answer is 63
