a. $1.3 \times 10^1$ b. $4.4 \times 10^7$ c. $6.1 \times 10^{-2}$
a. $1.3 \times 10^1$ is larger since its exponent is 1, which is greater than -2. b. $4.4 \times 10^7$ is larger since its exponent is 7, which is greater than 5. c. $6.1 \times 10^{-2}$ is larger since its exponent is -2, which is greater than -4.
