Answer: number 14 is 30.78 x 10 to the exponent of 11
Step-by-step explanation:
you multiply 8.1 and 3.8 together which would equal 30.78 and you add the exponents together since they are being multiplied.
k-1/2b=47 because the difference is subtraction and half b is a half fraction and it equals 47.
