Explanation:

Answer 2

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
