Answer 1

$\huge{\underline{\underline{\bold{\mathtt{\purple{✍A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍}}}}}}}}}}}}}}}}$$\huge{\rightarrow}$

—» $\mathtt{({2}^{5}×{2}^{8}){2}^{-7}}$

—» $\mathtt{{(2)}^{5+8-7}}$

—» $\mathtt{{2}^{6}}$

—» $\huge{\mathtt{64}}$

Answer 2

(2⁵ × 2⁸) 2^-7

2⁵+⁸ × 2^-7 [a^m × a^n = a^m+n]

2¹³ × 2-⁷ [a^m × a^n = a^m+n]

2¹³+(-⁷)

2¹³-⁷

2⁶
