Question

(1) (-4)2 ÷ (-4)3
it's the question of exponent.
we have to express the result in power notations with positive exponents. ​

Answer 1

Given,

$\tt{( - 4 {)}^{2} \div ( - 4 {)}^{3} }$

⇒ We know that, if the bases of any exponent are same, we must solve the powers;

$\tt{( - 4 {)}^{2} \div ( - 4 {)}^{3} } \\ \\ \tt{ = ( - 4 {)}^{2 - 3} } \\ \\ \tt{( - 4 {)}^{ - 1} }$
