Question :-

Write the expression using exponents.


0.8 \: · \: 0.8 \: · \: 0.8 \: · \: 0.8 \: = \boxed { ? }

___________________

Solution :-

Given Information :-

  • Expression ➢ 0.8 · 0.8 · 0.8 · 0.8

To Find :-

  • The value of the expression using exponents.

Calculation :-

Since, the expression is actually the repetition of 0.8, so we can write this as,

⇒ 0.8 · 0.8 · 0.8 · 0.8 = ( 0.8 )⁴

Calculating further, We get,

⇒ ( 0.8 )⁴ =
\sf (8 * 8 * 8 * 8)/(10 * 10 * 10 * 10) = (8⁴)/(10⁴)

⇒ ( 0.8 )⁴ =
(4096)/(10000)

Calculating further, We get,

⇒ ( 0.8 )⁴ = 0.4096

0.8 · 0.8 · 0.8 · 0.8 = ( 0.8 )⁴ = 0.4096

____________________

Final Answer :-

  • 0.8 · 0.8 · 0.8 · 0.8 = ( 0.8 )⁴ = 0.4096
