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 = $\sf \frac{8 \times 8 \times 8 \times 8}{10 \times 10 \times 10 \times 10} = \frac{8⁴}{10⁴}$

⇒ ( 0.8 )⁴ = $\frac{4096}{10000}$

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
