Solution:
[tex]4.21 \times {10}^{7} + 1.91 \times {10}^{7} [/tex]
- First take [tex] {10}^{7} [/tex]common from both the terms.
[tex] = {10}^{7} (4.21 + 1.91)[/tex]
- Now do the addition and subtraction of the bracket portion.
[tex] = {10}^{7} \times 6.12[/tex]
- Since you have to express the answer in scientific notation, so you don't need to do anything else.
- So, our required answer is [tex]6.12 \times {10}^{7} [/tex]
Answer:
[tex]6.12 \times {10}^{7} [/tex]
