The estimated number of dogs is 6.99 x 107 The estimated number of cats is 3.61 x 107 The estimated number of birds is 8.3 x 10 The power of 10 in 8.3 x 10 is 6, which is less than the power of 10 in the other two numbers. To make the calculation simpler, convert this number so the exponents are all the same. Multiply and divide 8.3 x 10 by 10 to increase its exponent by 1: 8.3 x 10% = 1.8.3 x 100 13.106.10 = 0.83 x 107 Part B Now that the three numbers have the same power of 10, find the sum using the Distributive Property.
