Answer 1

Answer: Brackets => 4 x (7)^2 - 5^2
Indices/Orders => 4 x 49 - 25

Multiplication => 196 - 25

Subtraction => 171

Answer 2

4•(2+5)^2 -5^2 = 171

Explanation:

Do BIDMAS
(brackets, indices, division, multipy, add, sub)

so brackets
4*7^2-5^2
then do the indices
4*49-25
then the multiply
196-25
= 171
Hope this helps
