Question

2.Using laws of exponents, simplify in the exponential form.

ii) a^3 * a^2 * a^7

Answer 1

**************************************

By Exponential Law :

x^m × x^n × x^p = x^m+n+p

**************************************

Now ,

a³ × a² × a^7

= a^3+2+7

= a^ 12

Therefore ,

a³ × a² × a^7 = a^12

Answer 2

exponential law
${x}^{a} \times {x}^{b} \times {x}^{c} = {x}^{a + b + c} \\ \\ \\ by \: using \: this \: law\\\\ so,\\\\ {a}^{3} + {a}^{2} + {a}^{7} \\ = {a}^{3 + 2 + 7} \\ ={a}^{12}$
