simplify (sqrt(4)+isqrt(4))+(sqrt(9)-isqrt(9))

simplify

(4 + i 4) + (9 - i 9)

5 - i

Solution steps

(4 + i 4) + (9 - i 9)

Rewrite

4 + i 4

in standard complex form:

4 + 4 i

Rewrite

9 - i 9

in standard complex form:

9 - 9 i

= 4 + 4 i + 9 - 9 i

Group the real part and the imaginary part of the complex number

(a + bi) + (c + d i) = (a + c) + (b + d) i

= (4 + 9) + (4 - 9) i

Simplify

(4 + 9) + (4 - 9) i : 5 - i

= 5 - i

(- 16)^{- \frac{3}{2}}

7 \geq \frac{3 - 4 x}{3}

10 x^{3} - 250 x

lo g_{3} (40) - lo g_{3} (10)

(3^{5})^{- 2} = \frac{1}{3 ^{- 10}}
