Question

$\underline{\underline{\sf{\maltese\:Question\::-}}}$

Write the answers for the following questions.

$\longrightarrow\bf\sqrt{x^{16}}$

$\longrightarrow\bf{49^{0.3}\times49^{0.2}}$

$\longrightarrow\bf{\dfrac{(7^6)^2}{7^7}}$

Answer 1

Answer:

$\sqrt{x^{16} }$

$=x^8$

 $49^{0.3}$ × $49^{0.2}$

= $49^{0.5}$  

= $49^{\frac{1}{2} }$

= $\sqrt{49}$

= 7

   $\frac{(7^6)^2}{7^7}$

= $\frac{7^{13} }{7^7}$

= $7^6$
