Question

What comes in the place of '*'?
(216)1.3×(36)1.8÷(6)0.5=6(216)^{1.3}×(36)^{1.8}÷(6)^{0.5}=6^*​​

Correct option is C

Given:
(216)1.3×(36)1.8÷(6)0.5=6(216)^{1.3}×(36)^{1.8}÷(6)^{0.5}=6^∗ 
To find: value of * 
Formula Used: 
(ax)y=ax×yax×ay=ax+yax÷ay=axy(a^x)^y = a^{x \times y} \\ a ^x \times a^y = a^{x+y} \\ a ^x \div a^y = a^{x-y}   
Solution: 
(216)1.3×(36)1.8÷(6)0.5=6(63)1.3×(62)1.8÷(6)0.5=6(63.9)×(63.6)÷(6)0.5=663.9+3.60.5=667=6 Comparing the power as Base is same,=7(216)^{1.3}×(36)^{1.8}÷(6)^{0.5}=6^∗ \\ (6^3)^{1.3}×(6^2)^{1.8}÷(6)^{0.5}=6^∗\\(6^{3.9})×(6^{3.6})÷(6)^{0.5}=6^∗ \\ 6^{3.9 + 3.6 - 0.5}=6^∗ \\ 6^7 = 6^* \\ \text{ Comparing the power as Base is same,} \\ * = 7 ​​​​
