Question

Express each of the following in exponential form:
(i) x × x × x × x × a × a × b × b × b
(ii) (−2) × (−2) × (−2) × (−2) × a × a × a
(iii) $\left(\frac{-2}{3}\right)\times \left(\frac{-2}{3}\right)\times x\times x\times x$

Answer 1

We have
(i) $x\times x\times x\times x\times a\times a\times b\times b\times b=x^4{a}^2{b}^3$
(ii) $(-2)\times (-2)\times (-2)\times (-2)\times a\times a\times a=(-2{)}^4\times a^3$
(iii) $\left(\frac{-2}{3}\right)\times \left(\frac{-2}{3}\right)\times x\times x\times x={\left(\frac{-2}{3}\right)}^2\times x^3$
