Write the product in standard form. (2.5×10-²) (3×10⁴)

(2.5 * 10^-2)(3*10^4)

7.5 * 10^2 = 750

so, it's standard form would be:

700 + 50

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
