Question

1)1,22×10⁶+3,79×10⁶2)9,5×10⁷-3,9×10⁷​

Answer 1

1) 1,22 * 10^6 + 3,79^6 = (1,22 + 3,79) * 10^6 = 5,01 * 10^6 = 5010000

2) 9,5 * 10^7 - 3,9 * 10^7 = (9,5 - 3,9) * 10^7 = 5,6 * 10^7 = 56000000

Answer 2

Sure, I can help you with those calculations. Let's solve each expression step by step:

1. $1.22 \times 10^6 + 3.79 \times 10^6$

To add these two numbers, we need to make sure they have the same exponent (power of 10). In this case, both numbers have the exponent of $6$, so we can directly add the coefficients:

$1.22 \times 10^6 + 3.79 \times 10^6 = (1.22 + 3.79) \times 10^6 = 5.01 \times 10^6$

So, $1.22 \times 10^6 + 3.79 \times 10^6 = 5.01 \times 10^6$.

2. $9.5 \times 10^7 - 3.9 \times 10^7$

Similar to the previous expression, we'll subtract the coefficients directly since both numbers have the same exponent ($7$):

$9.5 \times 10^7 - 3.9 \times 10^7 = (9.5 - 3.9) \times 10^7 = 5.6 \times 10^7$

So, $9.5 \times 10^7 - 3.9 \times 10^7 = 5.6 \times 10^7$.
