: 6x10(4 exponent)
2x10(-5 exponent)
is equal to 3x10 (9 exponent)
and is equal to 3,000,000,000
my question:
why isn't the exponent a negative 9 on 3x10 (9 exponent)? and why are we not using a decimal point here like we would in example:
8x10 (-9 exponent)
4x10 (3 exponent)
is equal to 2x10(-12 exponent)
is equal to 0.000000000002 This question is from textbook barrons algebra he easy way
