Question

youre trying to find the difference between 2.6×10⁴ and 0.5×10⁴. the power of 10 is the same, and 10⁴ means ten thousands. so you can think of this as 2.6 ten thousands minus 0.5 ten thousands. subtract 2.6 and 0.5 to find how many ten thousands there are.
2.6×10⁴ - 5×10³
= 2.6×10⁴ - 5×10⁻¹×10⁴
= 2.6×10⁴ - 0.5×10⁴
= (2.6 - 0.5)×10⁴
= □×10⁴

Explanation:

Step1: Subtract the coefficients

We have the expression $(2.6 - 0.5)\times10^{4}$. Subtract 0.5 from 2.6.
$2.6-0.5 = 2.1$

Step2: Get the final result

Multiply the result of the subtraction by $10^{4}$.
$2.1\times10^{4}$

Answer:

$2.1\times10^{4}$
