Question

2.3x10^4 x 1.5x10^-2 in standard form

Answer 1

Answer:

3.45x10^2

Step-by-step explanation:

2.3x1.5= 3.45

4-2=2= 10^2

Answer= 3.45 x 10^2

Answer 2

Answer:

The number in standard form is 345

Step-by-step explanation:

The given two multiplication of the numbers is

$2.3 \times {10}^{4} \times 1.5 \times {10}^{ - 2}$

First we multiply the non exponential terms as shown below

$2.3 \times 1.5 = 3.45$

Now we multiply the exponential terms as shown below

${10}^{4} \times {10}^{ - 2} = 10 {}^{4 - 2} = {10}^{2} = 100$

Now multiplying the exponential and non exponential term we get the number in standard form as shown below

$3.45 \times 100 = 345$

Therefore,the number in the standard form is 345
