Question

(3×10⁴)+(6×10³)+(9×10²)+(7×10¹)+(8×10°) is the same as ______ (a)34697 (b)36978 (c)306978 (d)3006978​

Answer 1

36978

Step-by-step explanation:

(3×10⁴)= 3 x 10,000= 30,000.

(6×10³)= 6 x 1000= 6000.

(9×10²)= 9 x 100= 900.

(7×10¹)= 7 x 10= 70. (any number raised to the power of "one" equals itself)

(8×10°)= 8. ( any number or expression raised to the power of zero is always equal to 1)

∴ 30,000+ 6000+ 900+ 70+ 8- 36978
