The value of (6^{5} )^{4}(6
5
)
4
Solution:
(6^{5} )^{4}(6
5
)

Use the rule of the exponents to simplify expression,
⇒ (6^{5} )^{4}(6
5
)
4
{ {(x^a)^b=x^{ab}}(x
a
)
b
=x
ab
}
To raise a power to another power, multiply the exponents,
⇒6^{5X4}6
5X4
Multiply 5 times 4,
⇒6^{20}6
20
It can be written as,
⇒2^{20}2
20
×3^{20}3
20
⇒3.6561583.656158 ×10^{15}10
