hat is the value of the expression in standard form?

(4.8×108)(2.2×10−6)(1.2×104)

The value of the expression in standard form is:

(4.8 x 10^8)(2.2 x 10^-6)(1.2 x 10^4)

To calculate the value, we multiply the numbers and add or subtract the exponents:

(4.8)(2.2)(1.2) x 10^(8-6+4)
= 12.672 x 10^6
= 1.2672 x 10^7

Therefore, the value of the expression in standard form is 1.2672 x 10^7.
