IRISSAK [1]

Answer:

A = 7.7

b = 26

Step-by-step explanation:

$(3.5 \times 10^{16})(2.2 \times 10^{10}) = A \times 10^b \\ 3.5 \times 2.2 \times 10^{16} \times 10^{10}= A \times 10^b \\ 7.7 \times {10}^{16 + 10} = A \times 10^b \\ 7.7 \times {10}^{26} = A \times 10^b \\ equating \: like \: terms \: on \: both \: sides \\ A = 7.7 \\ 10^b = {10}^{26} \\ \implies \: b = 26$
