Question

Write an addition expression and a subtraction expression, each with a value of 2.4 X 10 the power of negative 3.

Answer 1

Okay so first figure out what 2.4 times 10 with the power of negative 3 is.

2.4 times 10 is 24 and 24 to the power of 3 is 13,824

so an addition problem could be 5,986+7,838= 13,824

then you could do for a subtraction problem 23,789- 9,965 = 13,824

I hope this helped you. (;
