Question

how is the number below correctly expressed in standard form?
$2.75 \times 10^0$

• $2.75$
• $2,750$
• $0.0275$
• $27.50$

Explanation:

Step1: Recall the rule of exponents

Any non - zero number to the power of 0 is 1, so $10^{0}=1$.

Step2: Multiply the coefficient by the power of 10

We have the expression $2.75\times10^{0}$, substituting $10^{0} = 1$ into the expression, we get $2.75\times1=2.75$.

Answer:

A. 2.75
