Answer:

the value of 5^3 i^9 = 125 i

Step-by-step explanation:

We need to find the value of 5^3 i^9

'i' is a complex number (Imaginary)

The value of 5^3 = 5*5*5= 125

the value of i^2 =-1

i^3 = -i

i^4= 1

$i^9 = i ^{4+4+1}$

$i^9 = i^4 * i^4 * i$

$i^9 = 1*1 * i=i$

So the value of 5^3 i^9 = 125 i

Answer:

Step-by-step explanation:

3x squared+1

x=4

But remember PEMDAS

So 4 squared which is 16

3(16)+1

3x 16= 48 +1= 49

PLSSS HELP IF YOU TURLY KNOW THISS

KonstantinChe [14]

Answer: x=5

Step-by-step explanation:

$\frac{2x+0.8}{9}=1.2$

$\mathrm{Multiply\:both\:sides\:by\:}9$

$\frac{9\left(2x+0.8\right)}{9}=1.2\cdot \:9$

$\mathrm{Simplify}$

$2x+0.8=10.8$

$\mathrm{Subtract\:}0.8\mathrm{\:from\:both\:sides}$

$2x+0.8-0.8=10.8-0.8$

Simplify

$2x=10$

$\mathrm{Divide\:both\:sides\:by\:}2$

$\frac{2x}{2}=\frac{10}{2}$

Simplify

$x=5$

Anyone know how to do this

Oxana [17]

Answer:

9 sqrt(2) /2 = PQ

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp/ hypotenuse

sin 45 = PQ = 9

9 sin 45 = PQ

9 sqrt(2) /2 = PQ

Find the value of i77.<br> A) 1 <br> B) i <br> C) −1 <br> D) −i

Colt1911 [192]

assuming you mean $i^{77}$ where $i=\sqrt{-1}$

ok, notice a pattern in the exponent

$i^1=i=\sqrt{-1}$

$i^2=-1$

$i^3=-\sqrt{-1}=-i$

$i^4=1$

$i^5=i=\sqrt{-1}$

hum, so it goes 1,2,3,4, then repeats

ok, so every 4, the cycle repeats

how far up is 77 from a multipule of 4?

4*19=76

76 is 1 away from 77

so $i^{77}=(i^{76})(i^1)=$

$(i^4)^{19}(i)=(1)^{19}i=i$

the answer is B
