Question

calculate.
$(2.435 \times 10^9) - (1.7 \times 10^7)$
write your answer in scientific notation.

Explanation:

Step1: Make exponents equal

Convert \(1.7\times10^{7}\) to same exponent as \(2.435\times10^{9}\). \(1.7\times10^{7}=0.017\times10^{9}\)

Step2: Subtract the coefficients

Subtract: \(2.435 - 0.017 = 2.418\)

Step3: Write in scientific notation

Result: \(2.418\times10^{9}\)

Answer:

\(2.418\times10^{9}\)
