Olin [163]3 years ago
7 0
4^{x} + 1 = 64 \\4^{x} = 63 \\ln(4^{x}) = ln(63) \\xln(4) = ln(63) \\x = \frac{ln(63)}{ln(4)}

(\frac{ln(63)}{ln(4)})^{4} = 79.78006702

The value of x⁴ is equal to 79.8006702

Answer:

Step-by-step explanation:

a.18/-3  = (-6)

b.  -5/-1 = 5

c. 24/-6 = (-4)

d. -10/-1  = 10

e. -25/5 =(-5)

f.    8/-2 = (-4)

In multiplication and division, if there are are odd number of negative signs, the result will have negative sign.

If there are even number of negative signs, the the result will have positive sign

What is the next term of the following sequence? <br><br><br> 20, 10, 5, 21/2, ...
ycow [4]

Answer:

1 \frac{1}{4}

Step-by-step explanation:

Note there is a common ratio between consecutive terms, that is

10 ÷ 20 = 5 ÷ 10 = 2 \frac{1}{2} ÷ 5 = \frac{1}{2}

Thus to obtain the next term in the sequence multiply the previous term by \frac{1}{2}

2 \frac{1}{2} × \frac{1}{2} = 1 \frac{1}{4}

Grade 12<br>mathematics<br>(√98-√50)² ​
allsm [11]

Answer:

8

Step-by-step explanation:

Two different approaches:

<u>Method 1</u>

Apply radical rule √(ab) = √a√b to simplify the radicals:

√98 = √(49 x 2) = √49√2 = 7√2

√50 = √(25 x 2) = √25√2 = 5√2

Therefore,  (√98 - √50)² = (7√2 - 5√2)²

                                         = (2√2)²

                                         = 4 x 2

                                         = 8

<u>Method 2</u>

Use the perfect square formula: (a - b)² = a² - 2ab + b²

where a = √98   and   b = √50

So            (√98 - √50)² = (√98)² - 2√98√50 + (√50)²

                                      = 98 - 2√98√50 + 50

                                      = 148 - 2√98√50

Apply radical rule √(ab) = √a√b to simplify radicals:

√98 = √(49 x 2) = √49√2 = 7√2

√50 = √(25 x 2) = √25√2 = 5√2

Therefore,     148 - 2√98√50 = 148 - (2 × 7√2 × 5√2)

                                                 = 148 - 140

                                                 = 8
