(7 x 10 ^5) + (4 x 10 ^2)

spayn [35]

$\huge\text{Hey there!}$

$\mathsf{(7\times 10^5) + (4 \times 10^2)}\\\mathsf{= 7\times 10^5 + 4 \times 10^2}$

$\large\textsf{Let's solve for the LEFT SIDE first}$

$\mathsf{7\times 10^5}\\\\\mathsf{10^5}\\\mathsf{= 10\times10\times10\times10\times10}\\\mathsf{= 100 \times 100\times 10}\\\mathsf{= 10,000 \times 10}\\\mathsf{= 100,000}\\\\\mathsf{7\times100,000}\\\mathsf{= 700,000}$

$\large\textsf{NEW EQUATION: }\bold{700,000} + {4}\times 10^2$

$\large\textsf{Now, let's solve for the RIGHT SIDE last}$

$\mathsf{4\times 10^2}\\\\\mathsf{10^2}\\\mathsf{= 10\times10}\\\mathsf{= 100}\\\\\mathsf{4\times100}\\\mathsf{= 400}$

$\large\text{NEW EQUATION: 700,000 + \bf 400}$

$\large\text{700,000 + 400}\\\\\large\text{SIMPLIFY IT!}\\\\\large\text{= 700,400}$

$\huge\text{Therefore, the answer should be: \boxed{\mathsf{700,400}}}\huge\checkmark$

The geometric sequence a_ia i a, start subscript, i, end subscript is defined by the formula: a_1 = -\dfrac13a 1 =− 3 1 a,

slava [35]

Answer:

1.014*10^35

Step-by-step explanation:

Given the following geometric sequence

$a_1 = \frac{-1}{3} \\a_i = a_{i-1}*(-3)$

Sum of nth term of the GP is expressed as;

$S_n = \frac{a(1-r^n)}{1-r}$

a = -1/3

n = 75

r = a2/a1

a2 = -3a1

a2 = -3(-1/3)

a2 = 1

r = 1/(-1/3)

r = -3

Substitute the given values in the formula;

$S_n = \frac{-1/3(3^{75} - 1)}{3-1}\\S_n = \frac{3^{75}-1}{-6} \\S_{75} = 1.014*10^{35}$

Hence the sum of the first 75 terms is 1.014*10^35
